To all whom it may concer/it:-

Beit known that I, WILLIAM H. KELLER, a. citizen of the United States, residing in the' Vcity and county of'Philadelphia, State of Pennsylvania, have invented a new and use'- ful Vessel for the Conveyance or Storage of Liquids, of which thefollowing is especificational view of a portlon thereof.

It Iurther consists of other novel features toi construction, all as be hereinafter fully set forth.

' Figure 1 represents a vertical sectional.

view of a vessel for-conveying or "storing liquids. Fig. 2 represents a horizontal 'sec Fig?) re resents `a sectional view of a` ortion` of t e casing containing a slightly di erentformof connection between the bottom closure of the casing.y

Similarnulnerals of reference indicate correslponding parts in the figures.

eferringto th drawings :-I have found in practice in thevessels now in use upon the market for the conveyance or storage of liquids that it is'diiicult to appl the casing to the glass receptacles and to have access to the said receptacles should occasion arise. My invention is designed to overcome these defects and in the drawings I have shown an embodiment for carrying out my invention but'it will be evident that other instrumentalities may be employed and the arrangement oi the parts maybe varied without departing from the spirit of my invention and I do not therefore desire'tobe limited in every instance tothe exact construction as herein shown and described but desire to make such changesas may be necesse y.,

l designates a vessel for the conveyance or storage of liqluids, the same consisting` ot' the two receptac es 2 and 3, which are preferably oi' glass and suitably connected together, Aforming the space 4 therebetween from which the air is evacuated or exhausted,

forming a vacuum between the receptacles,

preferably of metal and beinformed to the walls of which having been previously supplied with asuitable coating of silver 5.

v 6 designates a casing which is adapted tol receive the receptacles, said casing being rO-r vide a space between it and t e outer su ace of the outer receptacle, in which space is ada ted to be seated, any suitable means for hol ing the receptacles in proper position. In the present instance I-have shown a corru; gated cardboard 7 for this purpose. The

neck of the casincgl 6 is formed with threads 8 turned downwar ly.

In orderto permit'of the insertion oi the` receptacles 2 and 3, I provide a removablev bottom cap 9 which is formed in any suitablenmanner and the walls 10 of which are adapted to en rage with the casing 6 so that said cap will be .positively held in osition,

1it being-understood that a suitable ictional engagement or connection is provided between the wall 10 and the wall of the casing l6 to insure that the cap is properly held in position. In some instances I may form a shoulder or stop-11. upon the inner wall of the casinor 6, against which the edge of the wall 10 ot the cap 9 abuts in order to prevent the improper positioning of said wall 10 with respect to the casing 6. The lower portion 12 o'ithe wall of the casing 6 may be slightly tapered and inclined inwardly in order to provide a positive frictional engagement between it and the wall l0 of the cap 9 for holding the parts in proper position. In some instances I may provide other means within the casing 6 against the edge of which means theupper edge of the wall 10i of the cap 9 abuts said ring thus serving as a shoulder or stop for the p arts and acts in the same manner as the sioulder 11.

As will be understood fromthe above I rovide a removable cap for the casing which 1s adapted to have rsuitable. engagement or connection therewith soAthat the parts cannot be accidentally separated but which permits ease of insertion of the receptacles into the casing, it being understood that any suitable means may be employed for connecting the parts in the desired manner.

'Having thus described mynvention.\vl1at casing and a stop internal of the easing for I claim as new and desire no secure by Letters limiting the relative movement of said cap l0 Pasnt! is: f h h v n b d and easing.
